From dee88f4378d18b4e7ebca22c82dab2ed5dfd178c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Antti=20Sepp=C3=A4l=C3=A4?= Date: Sat, 25 Jan 2014 06:57:46 -0300 Subject: [PATCH] [media] nuvoton-cir: Don't touch PS/2 interrupts while initializing MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There are reports[1] that on some motherboards loading the nuvoton-cir disables PS/2 keyboard input. This is caused by an erroneous write of CIR_INTR_MOUSE_IRQ_BIT to ACPI control register. According to datasheet the write enables mouse power management event interrupts which will probably have ill effects if the motherboard has only one PS/2 port with keyboard in it. The cir hardware does not need mouse interrupts to function and should not touch them. This patch removes the illegal writes and registry definitions.
